This is an odd one that I haven't found addressed anywhere else... All of my music files (wma) cut out 4 seconds too early. In other words, I can see that a particular track is 1:25 in length, but the song ends at 1:21 (I can see this on the player and hear the cutoff as well). This is quite annoying and is consistent with all of my music. With and without headphones. At first I was certain it was the MixZing app that I had just started using. But I've found this happens with the stock DX player as well. Any ideas???
